FAQ's

What are the advantages of users in good coverage with MIMO technology?

In MIMO UE experiencing good coverage (with high signal to noise ratios) can take advantage of the spatial multiplexing gain, receiving multiple parallel streams of data and enhancing its capacity.

What are the advantages of users in bad coverage with MIMO technology?

In MIMO UE experiencing bad coverage (with low signal to noise ratios) can take advantage of the MIMO Diversity gain to improve its signal to noise ratio and hence its capacity.

When is MIMO Rel.8 using beamforming?

For UEs in bad coverage (with low signal to noise ratios) there is a special MIMO Transmission Mode (TM 4) where beamforming using up to four antenna ports can improve its signal to noise ratio and hence its capacity.
